Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed December 19, 1914. Serial No. 878,020.

To all whom it may conce n Be it known that I, OTTO SPAHR, a citizen ofthe United States, residing at Philadeh to seal the bottle when not inuse but per" mit the milk to be poured from the bottle without removalof the closure, are known in the art; but the same are open tovariousobjections, such as inadequately tight closure, difficulty ofapplication and removal, imperfect provision'for proper outlet of themilk in pouring, expense of manufacture, etc. In an application filed byme August 15, 1914, Serial No. 856,937, I set forth an improvedclosure'in which these objections are substantially overcome.

The object of the present invention is to improve the closure set forthin said application, and particularly to insure the entire absence ofleakage in pouring, to render certain, after pouring, the return ofevery drop.

of liquid in the spout to the interior of the bottle, to preventbreakage'of the cap adjacent to the spout as a result of repeated use,and to strengthen the cap so that it will not suffer distortion as aresult of careless handling.

A preferred embodiment'of the invention is shown in the accompanyingdrawings, in which Figure 1 is a plan View of a cap embodying myinvention; Fig; 2 is a vertical sectional View of the cap applied to abottle; Fig. 3 is a view similar to Fig. 2 showing the bottle tiltedinto position to pour the contained liquid; Fig. 4 is aplan view of theblank for the capof Figs. 1, 2 and 3; Fig. 5 is a plan view of amodified form of blank.

From a flat piece of metal is cut a blank to disk a-(see Fig. 4) ofcircular contour except for the provision of a projection b to form thespout and projections c, 0 and d to form the holding flanges, bothhereinafter described. The piece is orificed at e and is cut to formnotches f extending beyond the outer corners of orifice e. The laterallyextending projection Z) is then bent at the corners and deflectedsomewhat upwardly to form a spout. Projections c, 0 and d are then bentdownward and curved to form holding flanges. Between the flanges themetal of the disk adjacent to the rim is bent downward to form areinforcing flange g. Between notches f the metal of the spoutportion 1) is bent down to form a lip 72., which acts as an innerextension of the spout and as an outer wall for the pouring orifice e. v

Immediately back of the pouring orifice e the disk a is cut away to forma slot 2'. This slot is preferably between the rear edge of the orificeeand the center of the disk and extends at a right angle to that radiusof the disk which intersects the center lineof the spout. A gate 70isprovided of sufficient area to cover orifice 6. The gate k has aflange m which extends through slot i. The flange is provided with acounterweight n.

It'will be observed that the dimension of the spout b measuringcircumferentially of the disk is substantially greater than thatdimension of the spout measuring radially beyond the disk. It will alsobe observed that the length of the pouring orifice after the lip hasbeen bent down as in Fig. 1 (measuring at right angles to that radius ofthe disk which intersects the center line of the spout is of about thelength of the spout. The endsof the pouringorifice are thereforeopposite points on the dge of the the orifice will necessarily flow tothe spout' and none of it will tend to flow over the edge of the diskbeyond the spout.

It isimportant, in pouring, that all the milk shall fiow out orifice eand that none of it shall escape between the under surface of ,the diskand the neck'of the bottle. This is insured by the provision of lip h;but to insure that the lip will be maintained tight against the insideof the bottle neck there are provided two holding flanges c, o, adjacentto spout b and only one holding flange d along the remainder of thedisk. Thus it is insured that the edge of the disk provided with thespout shall be held down against the bottle neck with greaterpressure'than the opposite edge of the spout is held down,

' whereby the lip h is held tightly against the inside of the bottleneck. This result is further insured by reason of the shape of theflanges which are curved on a smaller radius than the outer wall of therim of the bottle neck. The same result may be secured by constructingthe closure as in Fig. 5, in

which, for-a single flange d, are substituted three flanges 0, 0, 0,each substantially narrower, and therefore weaker, than either of theflangesc, c. The shape of the flanges gives to them the elasticityrequired to enable the cap to be readily applied and removed, while theengagement between the flanges and the bottle neck is such as to holdthe cap tightly down on top of the bottle and securely in position."

The narrow remforcing flange g is not intended to engage and ordinarilydoes not engage, the rim of the bottle neck, but the provision of thisflange reinforces'the disk so that it will not become distorted as are-' disk for a distance substantially greater than the width of thespout measured'radially of the disk, the disk back of said spout beingcut away to form a pouring orifice opposite ends of which extendsubstantially beyond radii of the disk between which the entire spout iscontained, and a movable gate for said orifice.

2. A bottle cap or closure-comprising a.

disk, a laterally extending upwardly inclined spout extending alongtheedge of the diskfor a distance substantially greater than the width ofthe spout measured radially of the disk, the disk back of said spoutbeing cut away to form a pouring orifice whose length, measured at aright angle to that radius of the disk extending along the center of thespout, is substantially greater than its width measured along saidradius,

and whose opposite ends extend substan- 1,15e,eea

tially beyond radii of the disk between which the entire spout iscontained, and a movable gate for said orifice.

3. A bottle cap or closure comprising a disk, a laterally extendingupwardly inclined spout projecting from the disk, there t being apouring orifice in the disk back of the spout, a downwardly bent lipalong the front wall of said orifice, two downwardly extending curvedflanges beyond and adjacent to opposite ends of the spout and locatedopposite the ends of said orifice, the semicircumference of the diskopposite the spout having a flanged portion of less strength than thefirst mentionedfianges, whereby when said disk is applied to a bottleneck with the flanged portion thereof engaging the outer wall thereof,the lip will be held firmlv against the inner wall of the bottle neck. i

4. A bottle cap or closure comprising a,

disk,'there being a pouring orifice in the diskand a slot adjacent tothe pouring orifice, a spout projecting from the disk in .front'of thepouring ori ce, a swinging gate for said orifice, and a weighted flangeon the gate extending through the slot and adapted to efiect the openingof the gate when the bot; tle is tilted toward a horizontal position.

5. A bottle can or closure comprising a disk, a laterally extendingupwardly in- .clined spout whose length, measured along the edge of thedisk, is substantially greater than its width measured radially of thedisk, the disk between its center and the spout being cut away to form apouring orifice whose length,- measured at a right'angle to that radiusof the disk extending along the center. of the spout, is substantiallygreater than its width measured along said radius and approximates thelength of the spout, and a downwardly bent lip along thefront wall ofsaid orifice adaptedfor engagement, with the inside of the rim of thebottle neck.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia,-on this 18th day of December, 1914.

OTTO SPAHR.
